Not sure what you’re trying to say here.
Since the indissolubility of marriage is a truth that has been accepted by all bishops throughout the world in the past, the teaching is infallible and dogmatically binding in the present and in the future. So even if all the bishops in the world decided tomorrow that marriage was no longer indissoluble, such an opinion wouldn't be binding. This is what makes Francis' praise of Kasper's serene theology so discordant.
